Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed January 2, 1909. Serial No. 470,281.

To all whom it may concern:

Be it known that I, ALBERT H. Mo- CUTCHAN, a citizen of the United States, residing at Helena, in the county of Alfalfa and State of Oklahoma, have invented a new and useful Nut-Feeding Attachment for Bolting-Machines, of which the following is a specification.

This invention relates to means for feeding nuts to bolting machines of that type disclosed in an application filed by me on February 29th, 1908, Serial No. 418,610.

rlhe object of the invention is to provide a feed attachment of this character which can be secured to a vbolting machine such as referred to and which will automatically supply nuts, one at a time, to the bolting machine.

Another object is to provide a feeding attachment of this character which is simple in construction and cheap to manufacture and which willnot easily get out of order.

A further object is to provide a feeding attachment whereby the nuts are held positively against displacement during the operation of shifting them from the reservoir to the bolting machine.

Tith these and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings F igure 1 is a front elevation of the attachment, showing the normal positions of the parts: Fig. 2 is an elevation, showing the opposite side of the attachment, with the parts in the positions assumed by them at the beginning of the nut-feeding operation: Fig. 3 is a front elevation of a portion of the attachment and showing the positions of the parts while av nut is being fed: Fig. 4 is a plan view of the attachment with the parts shown in the positions indicated in Fig. 1: Fig. 5 is a section on line A-B Fig. 4.

Referring to the figures by characters of reference 1 designates a supporting plate or standard designed to be bolted or otherwise fastened to the upper portion of a bolting machine, such, for example, as described in my application hereinbefore referred to. Extending inwardly from the upper edge of this plate or standard 1 is a table 2 and extending upwardly from the plate 1 at one side of this table is a flange 3 having an integral portion 4 which extends over and parallel with a portion of the table, said top portion being secured upon a guide strip 5 riveted or otherwise secured upon the table and disposed parallel with the ange 3. The space between the table 2 and the top portion 4 and between the strip 5 and the flange 3 constitutes a passageway in which a plunger 6 is designed to reciprocate. This plunger has a head 7 ixedly secured to one end and extending downwardly below the table 2, there being a spring 8 having one A end fastened to the downwardly projecting portion of the head, while its other end is secured to the plate or standard 1, as clearly indicated at 9 in Fig. 2. A bell crank lever 10 is pivotally mounted upon the plate or standard 1 and one arm of this lever is connected by a link 11 with the head 7 as shown at 12, while the other arm of the lever has a rod 13 attached to it and extending downwardly therefrom, said rod being end of the spout, as shown in Fig. 1. A'

magazine is arranged at one side of the spout 14 and 1s preferably in the-form of an upstanding casing 15, so proportioned as to hold nuts therein upon edge, the lower i end of the casing being curved so as to discharge the nuts on to the member 14 from one side thereof and with one face downward. This construction has been clearly indicated in Fig. 5.

Secured upon the top portion 4 of the table is a guide eye 16 in which is slidably mounted a retaining arm 17 pivotally connected at one end to the upper portion of the head 7 as shown at 18 in Fig. 4. The free end of this arm is curved downwardly and terminates in a foot 19 designed to normally rest in front of the plunger 6, there being a shoulder 20 upon the arm and adjacent said foot, which is designed to rest upon i in Fig. 2. The lowerniost nut will bear `against one side of the plunger 6 and all of the nuts will thus be held against downward movement.

Vhen it is desired to discharge a nut from thefeed device herein described the operator pulls Qn the rod 13 so as to swing bell crank Vvated as shown in said Fig. 2.

lever 10 on its fulcrum. This lever will push the plunger 6 backwardly against the stress of spring 8 until said plunger assumes theposition shown in Fig. Q, this movement vof thek plunger being such as to pull the arm 17 Vthrough the eye 16 and cause it to be elet-i-me the end of the plunger 6 will move past the outlet of the magazine 15 and the nuts Q1 contained in said magazine will move downward by gravity until the lowermost one assumes a position directly in front yof the plunger 6 and against the guide strip 5. By releasing the bell crank lever'l() the spring 8 will contract and will pull thev plunger 6 longitudinally along the table,

thus pushing ahead of it the nut lying in the path thereof. During the first stage of this forward movement of the nut the arm 17 moves downwardly through the eye 16 and the foot 19 assumes a position. upon the middle portion of the nut, thus holding it against upward displacement and insuring the positive actuation thereof by the plunger to the discharge end of the attachment. Upon repeating the operation above described another iiut can be fed from the attachment in the saine manner,

It will be seen that this device is very simple, durable and efficient, and constitutes means for positively supplying nuts, one at a time, to bolting machines. It therefore constitutes a very valu-able addition to machines such as set forth in my application y .hereinbefore referred to.

v Obviously various changes may be made in the construction and arrangement of the At the same Yparts without departing from the spirit or 4sacrificing the advantages of theinvention.

lVhat is claimed is 1. A device of the class described compris- Y ing a table, a guideY strip outstanding therefrom, a magazine extending upwardly from one side of the table, the lower portion of the magazine being open and arranged. .fto

direct objects'k laterally onto the. table and against the guide strip, a plunger' mounted to reciprocate upon the table, a pivotally mounted object retaining device above and movable with-the plunger, and'iixed means supported above the table for supporting one end of said device and for positively directing the device onto the object in the path of the plunger tohold said object against displacement during its actuation by ythe plunger.

2. A levice of the class described con'ipi'ising a table, a guide strip upstanding 'therefrom, a plunger slidably mounted on the table, and'a'magazine extending upwardly from the table for directing nuts by graif'ity onto the table from one side thereof and into the path of the plunger, said magazine 'constituting means for producing va one- 'quarter turn vof each nut during its move'- ment onto the table, and said plunger constituting means for sliding nuts one 'at a 'time from one end of the table. l

3. In a Amachine of the 'class 'described a table, a magazine for 'directing' nuts one at 'a time onto thet'able, said magazine constituting means for depositing nuts l'i'ipon the 'table with the bolt holes vperpeiidic'ularA to the bottom of the table, aplunger mounted to reciprocate upon `the table-to direct the nuts 'one at a time beyond one 'end `of the table, a pivoted nut retaining device 'mov-`VV ablewi'th the plunger and fixed means for supporting Vsaid device and for directing it ,ontothe nut in the path of the plunger,

said device having a shoulder fory engage- 'in'ent with the plunger upon the completion of one stroke of the plunger. y

In 'testimony that l claim the foregoing as `my own, I have hereto 'affixed my signature in the presence of two witnesses.
